FC Results: INR

INR predicts R-IFG-L-pSTS FC (z-scores), controlling for RMSD (not significant), dx (not significant), sex (not significant), and bilingualism (not significant) -- no significant dx by INR interaction. However, this association is no longer significant when controlling for SES1 (also not significant when controlling for INR, although they're both significant in the absence of one another)
